Make plugin deployment white-list based.

Deploy specific plugins instead of deploying all
plugins with exceptions.

Before macdeployqt would deploy nearly all plugins.
The plugins themselves weren't necessarily a problem,
but this would also pull in all plugin dependencies,
massively bloating the app bundle.
